Has anyone used a Dynon D10A as an indicator for VFR GPS yet? They are authorized for installation in PA28 via the EAA STC. The EAA install instructions leave out the instructions for connection and display of GPS nav info, so I'm wondering if that function is not authorized and I would still have to use a mechanical indicator if I wanted IFR GPS. My KLN90B authorizes use of EFIS for required annunciations and CDI and the D10A provides CDI info and GPS annunication in both AI and HSI modes.......
